Spirometry Results in Children over Five Years Old with COVID-19 at Least Six Months after Discharge

Introduction: Since it is necessary to detect changes in lung function for the follow-up of the patients with respiratory and functional complications caused by COVID-19, in this study, we decided to examine the results of spirometry in children over 5 years old with Covid-19. Methods: In this cross-sectional study, 52 over-five-year-old children, hospitalized due to COVID-19 for at least six past months, were examined. The participants’ demographic information, respiratory symptoms, underlying diseases, severity of COVID-19 according to WHO, severity of lung involvement in CT scan, type of lung involvement, oxygen saturation at admission as well as FEV1, FVC, and FEV1/FVC were collected and analyzed, the results were analyzed using SPSS version 16 software and t-test and Chi-square tests. Results: Of all investigated patients،, 26 were boys (50%) and 38 (73.1%) were 5-12 years old. The minimum age of the children was 5 years and the maximum was 18 years. The mean age of children was 3.41±10 years. The FEV1/FVC ranged from 61% to 79% in five patients (9.6%) and from 80% to 100% in 47 patients (90.4%). The FEV1 was lower than 80% in 28 and higher than 80% in 24 patients. FEV1/FVC had no significant relationship with the participants’ age, gender, clinical manifestations, and disease severity in terms of pulmonary involvement, but it had a significant association with blood oxygen saturation level (P: 0.001). Conclusion: The changes in pulmonary function tests vary in different months following contamination with COVID-19. In the present study, 9% of the patients, who were examined in the sixth month after infection, had abnormal pulmonary function test results. Based on the findings, the pulmonary function test results had no significant relationship with the patients’ age, gender, and clinical symptoms, while it was significantly associated with their blood oxygen saturation intensity.

Relationship of anxiety and depression with smoking cessation treatments: a follow-up study

ABSTRACT Background Smoking is known to be closely associated with a stress levels and anxiety. In this study, the effects of smoking cessation treatments were investigated on anxiety/depression. Methods Socio-demographic characteristics The Fagerström/Test/Nicotine/Dependence, the Hospital Anxiety and Depression (HAD) scale were applied at first time. The first group received “varenicline+counseling,” second group “bupropion+counseling,” and third group “counseling only.” The HAD scores were recorded in quit smokers. Anxiety and depression scores were compared between groups and between smokers and ex-smokers in the first and sixth month. Results Firstly, The HAD scores revealed that anxiety was present in 46.8%, depression in 11.2%, anxiety and/or depression in 48.9%. A significant decrease in both anxiety and depression scores was observed in quit smokers at 6 months (47.9% and 37.4%, respectively) (p < .001). At the sixth month, there was a significant decrease in anxiety scores in the varenicline and bupropion groups. In addition, a significant decrease in the depression score was observed in the varenicline group. In the bupropion group, the smoking cessation rate was higher in those with high anxiety and/or depression scores (66.7%). Conclusions Varenicline decreased anxiety/or depression scores in both smokers and quit smokers, whereas quit smoking rate increased in those with anxiety/depression in the bupropion.

The Synergistic Effects of Incobotulinum Toxin and Physiotherapy in a Rare Case of Paraparesis in a 7-Year-Old Affected by Klippel–Feil Syndrome Related to an MYH3 Gene Mutation: A Case Report

Background: Klippel–Feil disease is a condition characterized by a defect in the spine, consisting of the fusion or non-separation of two or more vertebrae of the cervical tract. It affects 1 in every 50,000 newborns, and the pathogenesis remains unknown to date, although the role of certain genes that are involved in segmentation processes is being studied. A single case of a genetic Myosin Heavy Chain 3 (MYH3) mutation is described here. Affected patients are typically distinguished by a relatively short neck, which leads to limited mobility, a low hairline, and obesity; they may also experience various other health issues. The common occurrence of comorbidities further diminishes the quality of life of these young individuals. Methods: The following case report describes the synergistic effect of Incobotulinum toxin type A and physiotherapy in a 7-year-old patient with MYH3 mutation-related Klippel–Feil syndrome (KFS) complicated by bilateral paraplegia to improve the spasticity condition of the lower limbs. To assess improvements over time, the patient underwent rating scales to determine spasticity (Modified Ashworth Scale: MAS), the neck’s range of motion (ROM), and muscle tone by using MyotonPro®. Specifically, measurements were taken on the day of the first medical examination (T0), the month after the injection and the startup of therapeutic exercise (T1), at three months (T2), and then once a month for a total of 6 months (T3, T4, and T5). Results: This therapeutic approach resulted in highly satisfactory outcomes for the child’s well-being, which was maintained until the sixth month and was accompanied by a complete absence of any side effects.

The role of hemoglobin A1c as a predictor of major adverse cardiovascular events in patients with type 2 diabetes mellitus after percutaneous coronary intervention: a case-cohort study

BackgroundFew studies have investigated the potential predictive value of glycosylated hemoglobin A (HbA1c) and clinical outcomes in diabetic patients after percutaneous coronary intervention (PCI), and the results of the reports have often been inconclusive and contradictory. We have organized a study to investigate the relationship between HbA1c and the occurrence of major adverse cardiovascular events (MACE) in diabetic patients after PCI.MethodsThis case-cohort study was conducted on 563 diabetic patients who underwent PCI. All studied patients had an HbA1c level measured within 24 h before angioplasty. All patients were followed for six months regarding the occurrence of MACE, and the HbA1c level was measured again at the end of the sixth month of follow-up. In the case of MACE, the subjects were considered the case group, and other non-MACE patients were included in the control group.Results505 patients remained in the study at the end of follow-up. MACE occurred in 23 (4.6%) patients during the first month and in 57 (11.3%) patients by the end of the sixth month. Baseline HbA1c was an independent predictor of MACE and mortality at the end of month-6 (P = 0.008 and 0.001, respectively).ConclusionsThe level of HbA1c at the time of admission has a significant predictive value for the occurrence of MACE in diabetic patients who undergo PCI. However, post-PCI glycemic control may not effectively reduce the risk of MACE in this population.Clinical trial registrationNot applicable.

Ahmed's sub-flap mattress suture deep sclerectomy assessment with Ultrasound Biomicroscopy.

To assess the efficacy of adding Ahmed's sub-flap mattress suture to deep sclerectomy (DS). Forty eyes with open angle glaucoma were assigned randomly into two groups: Group A: underwent DS with Ahmed's sub-flap mattress suture. Group B: underwent conventional DS. Patients were followed up closely for 6 months with serial IOP measurements and ultrasound biomicroscopy (UBM) was used to assess the surgical site functionally and anatomically at the first and sixth month. Adding Ahmed's sub-flap mattress suture improved the IOP lowering effect of DS significantly from 43% in group B to 53% in group A at 6-month (p = 0.027). IOP in group A was at 1 week, 1 month and 6-month visits (7.9 ± 1.3, 11.7 ± 2.2 and 13.3 ± 1.9 mmHg respectively) compared to group B (10.1 ± 4.6, 14.1 ± 5.2 and 16.8 ± 4.1 mmHg respectively) (p = 0.025, 0.041 and 0.001 respectively). UBM parameters were significantly larger in group A at 1 and 6 months. Strong statistically significant negative correlations were established between IOP and all the UBM parameters apart from intrascleral lake height at the first and sixth month (p < 0.01 in all of them). Finally, significant correlations were found between IOP at 6 months and whole bleb anteroposterior length and height at 1 month (p = 0.001). Adding Ahmed's sub-flap mattress suture to routine DS is an effective economical addition that will enhance the IOP lowering effect of DS. Also, assessment of the bleb by UBM is useful in predicting the success of deep sclerectomy surgery.

Challenging Childhood Obesity: The Influence of Education and Close Monitoring on Obesity-Related Behaviors.

We aimed to evaluate the role of nutrition and behavior education intervention in the prevention and treatment of childhood obesity by comparing changes in obesity-related characteristics among obese children during a follow-up period of 12 months. This study was designed as a prospective cohort study in children aged between 6 and 18 years, with exogenous obesity who applied to Istanbul Research and Training Hospital, Pediatrics Department, between January 2018 and July 2019. Beginning at the sixth month, a program for nutrition and behavior education for obesity prevention and treatment was initiated and continued during the second half of the study period. The mean age of 59 children (29 females, 30 males) was 11.73 ± 2.78. BMI levels did not show a significant difference in the first 6 months, but decreased significantly during the second 6 months of the study. Screen time, fast eating behavior, overeating behavior and food score index scores also demonstrated significant improvements during the intervention period of the study, between 6 and 12 months. It was concluded that nutrition and behavior education for the prevention and treatment of childhood obesity could be a successful intervention with close follow-up.

Circumferential patellar denervation does not reduce anterior knee pain in total knee arthroplasty without patellar resurfacing; a prospective comparison

BackgroundThis study aimed to evaluate the effectiveness of circumferential patellar denervation in reducing anterior knee pain (AKP) and improving clinical outcomes after total knee arthroplasty (TKA) without patellar resurfacing.Materials and methodsThis prospective, non-randomized, observational study included patients who underwent primary TKA at our institution between August 2023 and January 2024. Patients were divided into two groups: those who received patellar denervation (PD group) and those who did not (NPD group). The primary outcome was the reduction in anterior knee pain (AKP), measured by the Visual Analog Scale (VAS). Secondary outcomes included the Kujala Knee Score, Western Ontario and McMaster Universities Arthritis Index (WOMAC), and range of motion (ROM). Assessments were conducted preoperatively and at 3 and 6 months postoperatively.ResultsFour patients in the PD group and five in the NPD group were excluded from the study due to failure to complete follow-up. Thus, 74 female and 16 male patients with a mean age of 67.4 ± 4.2 years were included in the final analysis. There were no significant differences between the two groups with respect to age, sex, side of surgery, height, weight, BMI, grade of patellofemoral osteoarthritis, preoperative ROM, VAS score, Kujala score, and WOMAC score (p: n.s. for all variables). No significant differences were found between the groups for VAS, Kujala, and WOMAC scores at any time point (p: n.s.). Significant improvements in these scores over time were indicated by repeated measures ANOVA (p = 0.001 for both groups). Pairwise comparisons showed significant improvements from preoperative to postoperative months three and six and from postoperative months three to six (p = 0.001 for all comparisons). Both groups experienced decreased knee ROM at third month, which returned to preoperative values at sixth month with no significant differences. No complications were observed during the study.ConclusionsCircumferential patellar denervation does not provide additional benefit in reducing anterior knee pain or improving functional outcomes compared to the non-denervation approach in TKA without patellar resurfacing.Level of evidenceLevel III, Prospective comparative study.

Could macrocytosis predict survival In advanced breast cancer patients that were treated with CDK 4–6 inhibitors?

IntroductionCyclin Dependent Kinase (CDK) 4–6 inhibitors are the recommended first-line treatment option for hormone-positive metastatic breast cancer (MBC). They show their effects by causing cell cycle arrest in G1-S phase. Neutropenia is the most common haematological side effect. In the literature, data on the association between CDK 4–6 inhibitors and macrocytosis are limited. We aimed to investigate the effect of macrocytosis on survival. MethodsWe retrospectively analysed 133 patients with de novo hormone positive MBC using CDK 4–6 inhibitors in first line treatment. Mean Corpuscular Volume (MCV) > 100 was considered macrocytosis and patients were divided into two groups; MCV<100 and MCV >100. The association of macrocytosis with clinicopathological features, Progression Free Survival (PFS) and Overall Survival (OS) were evaluated. Results42 patients were receiving palbociclib and 81 patients were receiving ribociclib. Median OS was determined as 33 months and median PFS was determined as 22 months. Macrocytosis ever rate was 45.8 % during follow-up. Macrocytosis was observed in 4.2 % of the patients in the first month, 16.7 % in the third month, 41.6 % in the sixth month and 42.2 % in the twelfth month. ER receptor level, ki-67, macrocytosis at 6–12 months and macrocytosis-ever which were found to affect OS as a result of univariate Cox regression analysis, were evaluated with multivariate Cox regression models and it was observed that they had significant effect on PFS and OS. ConclusionMacrocytosis may be a useful biomarker for the prediction of PFS and OS in MBC patients receiving CDK 4–6 inhibitors.

Interprofessional In Situ Simulation’s Impact on Healthcare Personnel’s Competence and Reported Need for Training in Cardiopulmonary Resuscitation—A Pilot Study in Norway

Background/objectives: International guidelines recommend cardiopulmonary resuscitation [CPR] training every sixth month. However, research indicates that more training is needed to maintain CPR competence. The objectives of this pilot study were (a) to assess health personnel’s self-reported competence and need for more training in CPR before and after interprofessional in situ CPR simulation and (b) to assess time since the last CPR course and respondent’s reported need for more training. Also, we wanted a pilot to assess areas of improvement in a future, larger study. Methods: A questionnaire was administered to healthcare personnel in hospital wards receiving CPR training using a purposeful sampling strategy. Results: In total, 311 respondents answered the pre-intervention and 45 respondents answered the post-intervention survey. The respondents believed they had good knowledge, skills, and training in CPR, and about 2/3 of the respondents reported a need for more knowledge, skills, and training. There was a weak positive correlation between the time since the last CPR course and the perceived need for more training [p &lt; 0.05]. There were no significant differences in self-reported competence or perceived need for more training pre- and post-intervention. The pilot detected several limitations that need improvement in a future study. Conclusions: The authors suggest that regular training is important for maintaining competence in CPR. Also, in a future study, comparisons at an individual level, as well as assessments by experts and of non-technical skills, should be included.

Effects of D3K2 With Periodontal Therapy in Diabetes Mellitus and Stage I-II Periodontitis Patients.

The aim of this study is to look into the clinical and biochemical outcomes of D3K2 supplementation in addition to nonsurgical periodontal treatment (NSPT) for patients suffering from diabetes mellitus (DM) and periodontitis. Thirty-eight participants with DM and periodontitis were randomized into two different groups. The test group provided NSPT with D3K2 whereas the control group received NSPT with placebo. Clinical periodontal parameters were recorded and serum and gingival crevicular fluid (GCF) were sampled at baseline and at the third and the sixth months after treatment. Glycated hemoglobin A1c (HbA1c), fasting blood glucose (FBG), 25(OH)D3, parathyroid hormone (PTH), calcium (Ca) and magnesium (Mg) values were determined in blood samples. GCF and serum interleukin (IL)-1β and IL-10 levels were analyzed using enzyme-linked immunosorbent assay. All clinical periodontal parameters were importantly decreased at the third and sixth months after treatment compared to baseline in both groups. At the sixth month, 25(OH)D3 levels in the test group were observed to be statistically significantly higher than in the control group (p = 0.02). Serum IL-1β showed a statistically significant decrease at the sixth month compared to baseline and the third month in control group. According to this study, there is limited additional benefit of D3K2 given with NSPT in individuals with DM and periodontitis.

6662 Effect of Selenium Supplementation on Mild Graves’ Ophthalmopathy at a Tertiary Hospital - A Six-Month Open-Labelled, Assessor-Masked, Randomized-Controlled Trial

Abstract Disclosure: J.M. Flores: None. N.G. Sioson: None. J.D. Uy-Ho: None. A.L. Suller-Pansacola: None. Graves’ orbitopathy is associated with increased oxidative stress. Selenium, with its antioxidant and immunoregulatory actions, has been proposed as an adjuvant therapy. Objective: This study was undertaken to determine whether selenium supplementation for six months can decrease signs and prevent worsening of mild Graves ophthalmopathy among Filipinos. Methods: We conducted an open-labelled, assessor-masked, Randomized-Controlled Trial on patients with mild Graves’ ophthalmopathy wherein one arm was assigned to standard of care (eye drops) only for a period of six months while another arm was assigned to 200 ug/day oral Selenium supplementation alongside standard of care. Population: Adult patients with Graves’ hyperthyroidism, with at least one sign of mild ophthalmopathy with GO disease duration of less than 18 months Results: Independent Sample T-test, Mann-Whitney U test and Fisher’s Exact/Chi-square test were used to determine the difference of mean, rank and frequency, between patients given Selenium versus patients given standard of care. Paired Sample T-test, Wilcoxon Sign rank test and McNemar test were used to determine the difference of mean, rank and frequency on patients from initial to 3rd month or 6th month observation. Null hypotheses were rejected at 0.05α-level of significance. There was a significant difference in Clinical Activity Score (CAS) between patients given selenium supplementation and those assigned to standard of care. On initial examination for the Selenium group, 14 eyes (33.33%) had a CAS score of 0, which increased to 27 eyes (64.29%) on the third month and ended to a 26 eyes (61.9%) at the sixth month of treatment. For the non-selenium group, 11 eyes had a CAS score of zero initially, increased to 16 eyes (and 38.1%) then finally arrived to a total count of 14 eyes (33.33%). Improvement in CAS may be attributed specifically to improvement in caruncle/plical swelling showing a significant difference (p-value 0.040). Comparing the two groups, a statistical significance in CAS is noted between the treatment versus the control group with a p-value of 0.017 on the 6th month. Conclusion: Selenium supplementation provided significant benefit in terms of decreasing signs and preventing worsening of mild GO through improved CAS score. Further studies exploring the baseline and end of treatment selenium concentrations in the Philippines may be warranted. Presentation: 6/3/2024

Centchroman and tamoxifen in mastalgia: A randomized controlled trial

BackgroundMastalgia can be incapacitating for some individuals, necessitating medical intervention. Only a limited number of drugs have demonstrated effectiveness in managing the symptoms. An emerging option is oral centchroman, purported to be effective in this condition. Clinical trials are necessary to determine its role in the treatment of mastalgia. MethodsAn evaluator-blinded randomized controlled trial was conducted at a tertiary care teaching hospital to compare the efficacy of tamoxifen 10 mg and centchroman 30 mg daily. The study aimed to investigate the effect of treatment on the Visual Analog Scale (VAS) score of pain and the number of painful days per menstrual cycle or month. Following appropriate exclusion and randomization procedures, 51 patients completed the treatment and follow-up. ResultsCentchroman was more effective in controlling pain in the first month (p =0.04). No significant difference in the VAS score of pain was observed at the third or sixth month. Both drugs were effective in reducing the number of painful days, with no statistically significant difference between them. The recurrence rate at the sixth month was also not different (P = 0.41). Overall, 32% of patients on centchroman and 38.4% of patients on tamoxifen either failed to achieve satisfactory pain relief or experienced recurrences. ConclusionCentchroman is a safe and effective substitute for tamoxifen, demonstrating superior early symptom control, albeit with a slightly increased occurrence of adverse effects. In the event that no symptomatic relief is observed within a one-month trial of either medication, discontinuation is recommended, as prolonged use is unlikely to yield additional relief.

The effect of blood flow-restrictive resistance training on the risk of atherosclerotic cardiovascular disease in middle-aged patients with type 2 diabetes: a randomized controlled trial.

The aim of this study was to investigate the effects of blood flow-restrictive resistance training (BFR-RT) on improving metabolic abnormalities, blood pressure (BP), obesity, and 10-year atherosclerotic cardiovascular disease (ASCVD) risk in middle-aged patients with type 2 diabetes mellitus (T2DM). We conducted a parallel-group, single blind randomized controlled trial. Participants who met the inclusion criteria were randomly divided into control group, BFR-RT group and aerobic exercise (AE) group. Control group received health education and follow-up; Two exercise groups received supervised collective training for a period of six months, three times per week. AE group trained at moderate-intensity for 60 minutes each time, while BFR-RT group trained at low-intensity for 40 minutes each time. The primary outcomes were change in 10-year ASCVD risk index and level, and the secondary outcomes included changes in fasting plasma glucose (FPG), glycosylated hemoglobin (HbA1c), blood lipids, BP, and obesity level within and across the three groups at baseline, the third and sixth months of intervention. Among 93 individuals (control group, n=31; AE, n=30; BFR-RT, n=32) were analyzed. At baseline, there were no significant differences in various indicators among the three groups (p>0.05). After intervention, the 10-year ASCVD risk index and risk level of both exercise groups significantly decreased compared to the control group and baseline (p<0.05), and the risk reduction became more pronounced over time. In the sixth month of intervention, the 10-year ASCVD risk index in the AE group decreased by 27.40%, and that in the BFR-RT group decreased by 26.78%. Meanwhile, apart from lipoprotein (a) and diastolic blood pressure, both exercise groups showed significant improvements in FPG, HbA1c, dyslipidemia, systolic blood pressure, and obesity indicators compared to the control group and baseline (p<0.05). There was no significant difference in various indicators between the two exercise groups (p>0.05). BFR-RT could reduce the 10-year ASCVD risk in middle-aged T2DM patients for by improving metabolic abnormalities, BP and obesity, and its effect was similar to that of moderate-intensity AE. https://www.chictr.org.cn/showproj.html?proj=178886, identifier ChiCTR2300074357.

ONLINE LECTURE DURING THE COVID-19 PANDEMIC AFFECTS MEDICAL STUDENTS' LEARNING OUTCOMES BASED ON MCQ SCORE EXAMINATION

The COVID-19 pandemic has made major changes, one of which is the policy of implementing online lectures from home. This change in method can affect student learning outcomes that can be observed through the results of the MCQ exam at the end of the block. This study was conducted to determine the influence of online lectures during the COVID-19 pandemic on the results of the final MCQ test of student blocks. The retrospective cohort research design was carried out by collecting the MCQ scores at the end of the block at the time before the pandemic, the beginning of the pandemic and the sixth month of the pandemic from students of the 2017, 2018, and 2019 batches and data analysis was carried out by means of the Friedman Test, the Repeated Anova test, the Kruskal-Wallis test and the One-Way Anova. In the class of 2017, the average MCQ test results of the final block before, at the beginning, and in the sixth month of the pandemic were 50.72+8.02 consecutively; 51,39+6,8; 50.31+8.41, and there was no significant difference between them (p&gt;0.001). Meanwhile, in other batches, a significant difference (p&lt;0.001) was found with the results of the final MCQ exam in the 2018 batch of 45.29 + 7.87; 42.77 + 10.4 and 50.68 + 10.63 and for the class of 2019 it is 62.00 + 6.83; 46.8+10.92 and 52.32+10.02. At the beginning of the implementation of online lectures, the final MCQ score of the junior student block was most affected (p&lt;0.001). The online lecture method affects the learning outcomes of first- and second-year students but not for third-year students.

Repeated subcutaneous esketamine on treatment-resistant depression: An open-label dose titration study

BackgroundKetamine has recently gained prominence as one of the most effective therapeutic options in unipolar treatment-resistant depression (TRD). However, most studies related to the antidepressant action of ketamine used intravenous (IV) or intranasal (IN) administration. The subcutaneous (SC) route of administration is a promising alternative, as it results in plasma levels comparable to IV, causes fewer side effects, and is easier and cheaper to administer than both IV and IN routes. MethodsIn this context, we conducted an open-label clinical trial for investigating the efficacy and safety of 8 weekly sessions of SC esketamine in TRD patients (n = 30). ResultsAt the end of the treatment, a partial response rate of 26.09 %, a response rate of 52.17 % and remission rate of 34.78 % were observed. The self-reported depressive symptoms, as measured by the Beck Depression Inventory II, significantly decreased from the baseline to the final session, and the improvements were sustained throughout the week. Follow-up evaluations up to the sixth month consistently showed scores lower than the baseline. LimitationsThe small sample size and the drop-out during the follow-up phase may limit the generalizability of the findings. Additionally, the absence of a control group necessitates cautious interpretation of causality. ConclusionsThis pioneering study, which addresses SC esketamine treatment for TRD, reported promising response and remission rates, as well as sustained effects. It highlights the need for further research to improve and expand our knowledge of this innovative, more accessible, and cost-effective therapeutic approach.

Evaluating the Effects of Decentralized District-Based Treatment of Drug-Resistant Tuberculosis in Pakistan: An Alternative Model of Care

Background: Pakistan faces a high burden of drug-resistant tuberculosis (DR-TB), with traditional centralized care resulting in delays and poor treatment outcomes. Decentralizing care to district-level hospitals offers a potentially more effective alternative.Objective: This study aimed to evaluate the impact of decentralized DR-TB care on treatment initiation time, patient follow-up, and treatment outcomes.Methods: A descriptive post-intervention study was conducted at a decentralized DR-TB clinic in Sheikhupura, Punjab, between June 2021 and December 2022. Data from 100 patients were retrospectively collected from hospital records and diagnostic labs, including demographic information, treatment compliance, smear and culture conversion rates, and adverse drug reactions. SPSS 25 was used for statistical analysis, including descriptive statistics.Results: The average time from diagnosis to treatment initiation was 14.9 days. Smear conversion by the sixth month was 99%, while culture conversion was 98%. The treatment success rate was 70%, with a 7% loss to follow-up, 2% treatment failure, and 15% mortality.Conclusion: Decentralized DR-TB care significantly reduced delays in treatment initiation and improved patient outcomes. This model is feasible for national implementation with potential to enhance DR-TB management in Pakistan.

Outcome Prediction by Diffusion Tensor Imaging (DTI) in Patients with Traumatic Injuries of the Median Nerve.

Background/Objectives: The accurate quantification of peripheral nerve axonal regeneration after injury is critically important. Current strategies are limited to detecting early reinnervation. DTI is an MRI modality permitting the assessment of fractional anisotropy, which increases with axonal regeneration. The aim of this pilot study is to evaluate DTI as a potential predictive factor of clinical outcome after median nerve section and microsurgical repair. Methods: We included 10 patients with a complete section of the median nerve, who underwent microsurgical repair up to 7 days after injury. The follow-up period was 1 year, including the current strategy with clinical visits, the Rosén-Lundborg score and electroneuromyography. Additionally, DTI MRI of the injured wrist was planned 1, 3 and 12 months post-operatively and once for the contralateral wrist. Results: The interobserver reliability of DTI measures was almost perfect (ICC 0.802). We report an early statistically significant increase in the fractional anisotropy value after median nerve repair, especially in the region located distal to the suture. Meanwhile, Rosén-Lundborg score gradually increased between the third and sixth month, and continued to increase between the sixth and twelfth month. Conclusions: DTI outcomes three months post-operation could offer greater predictability compared to current strategies. This would enable faster decision-making regarding the need for a potential re-operation in cases of inadequate early reinnervation.

Trajectories and predictors of gerontological service career adaptability among health science undergraduates: A longitudinal study

BackgroundIn response to the aging population, it is essential to examine gerontological service career adaptability among health science undergraduates. ObjectivesThis study aimed to clarify the trajectories and predictors of health science undergraduates' gerontological service career adaptability. DesignThis study adopted a longitudinal design. SettingsThis study was conducted at four universities in China. Participants and methodsHealth science undergraduates were recruited via convenience sampling. Data were collected in the third (Stage 1), sixth (Stage 2), and ninth (Stage 3) months of the participants' graduation year. A total of 471 undergraduates completed a three-stage self-report questionnaire that assessed gerontological service career adaptability, career motivation, proactive personality, and practice environment at Stage 1 and gerontological service career adaptability at Stages 2 and 3. The response rate was 76.84 %. Data analyses entailed multiple linear regression, a latent growth mixture model, and multiple logistic regression. ResultsThree subgroups representing different gerontological service career adaptability trajectories were identified: rapidly growing (6.16 %), stably growing (87.47 %), and decreasing (6.37 %). Changes were observed primarily from the third to sixth months of the participants' graduation year. Health science undergraduates with high career motivation and a strongly proactive personality were likely to be in the decreasing group, whereas those with a supportive practice environment were predisposed to belong to the decreasing and stably growing groups. ConclusionsThe health science undergraduates' gerontological service career adaptability trajectories are heterogeneous, with the critical period spanning the third to sixth months of their graduation year. Gerontological service career adaptability grows stably among most undergraduates who have a supportive practice environment. Additionally, gerontological service career adaptability changes easily among undergraduates with high career motivation and a strongly proactive personality. Educators should implement tailored interventions to enhance gerontological service career adaptability based on health science undergraduates' traits.

Early oral colonization of streptococcus mutans and lactobacilli species in infants: Investigating the relationship with maternal and environmental factors, from birth through the sixth month.

To assess the presence of Streptococcus Mutans (S.mutans) and Lactobacillus species (LB) of newborn-mother pairs using the real time polymerase chain reaction (qRT-PCR). Subjects were selected from the patients followed in the Neonatology Clinic of Akdeniz University's Faculty of Medicine between the years 2017-2018. First samples collected within 48 hours after birth, and second samples were at six months. The samples were analyzed for the presence of S.mutans and LB using qRT-PCR. Mothers' smoking habits, education level, occupation, oral hygiene habits, DMFT scores and dietary history; Babies' delivery type, birth weight, feeding type, oral hygiene practices, feeding habits, bottle usage, pacifier usage, consumption of sugary foods, were also recorded. The effect of factors related to both mothers and infants was examined comparatively. S.mutans DNA was detectable in 87% and LB DNA was detected in 37% mothers, while it was undetected in 63% mothers at the first sampling. S.mutans was detected in 37% and, while LB was detected in 5% of the newborns in the first 48 hours of their life. At the second sampling, the S.mutans and LB levels in infants have increased, while there has been no significant change in mothers. A significant relationship was found only between the increase in S.mutans in infants and the presence of erupted teeth. S.mutans and LB were able to colonize on the oral mucosal surfaces of edentulous newborns, with the counts of both bacteria increasing significantly with tooth eruption.

Impact of an emergency department nurse training intervention on the adequacy of thromboprophylaxis for venous thromboembolism: the PROTESU III study.

Objectives. To assess the impact of training for emergency department (ED) nurses on adequate thromboprophylaxis for patients admitted to hospital from the ED for medical conditions. Methods. Multicenter quasiexperimental pre-post study of an ED nurse training intervention in 8 hospitals. Patients were recruited from January 2022 through May 2023 in 3 phases: before nurse training, in the first month after training, and in the sixth month after training. Included were patients attended in the ED for medical conditions. Adequate thromboprophylaxis was defined as 1) use of prophylactic drugs in patients at high risk for venousthromboembolism according to the Padua Prediction Score (PPS), and 2) nonuse in patients at low risk. We compared the percentage of adequate prophylaxis in the first phase to the percentages in the second and third phases. Results. A total of 928 patients were included (326 in phase 1, 295 in phase 2, and 307 in phase 3). PPS scores indicated that 238 (73%) of the patients were at high risk in phase 1 vs 189 (64.1%, P = .016) in phase 2 and 207 (67.4%, P = .125) in phase 3. A total of 187 patients (57.4%, 95% CI, 51.8%-62.8%) were adequatelythromboprophylaxed in phase 1 vs 178 (60.%, 95% CI, 54.5%-66%) in phase 2 (absolute difference in proportions, 3.0% (95% CI, -4.8% to 10.6%; P = .462)]. In phase 3, 166 patients (54.1%, 95% CI, 48.3%-59.7%) received adequate prophylaxis (difference, -3.3% (95% CI, -11.0% to 4.4%; P = .405). Conclusions. A training intervention for ED nurses, implemented as an isolated strategy, had no impact on the adequacy of thromboprophylaxis in patients admitted from the ED for medical conditions.
